Symptoms?!

Elizabeth
AF is due on Tuesday (14th)... I'm currently 11dpo. I took tests at 8 & 9 dpo but got BFN... 
—I'm starting to feel cramps but they're not like period cramps. (It's hard to explain how it feels) my CM is now creamy and increasing. My nipples are a bit sore & I've had some lower back pain the past 2 days. I'm waiting until after AF is due to test again & im not trying to get my hopes up but it's hard with these symptoms! 
Is there anyone that had similar symptoms and got a BFP?!?!
